I’d be curious to know whether the beetles prey upon ant larvae (as with Martinezia dutertrei on Solenopsis invicta), acquire food through strigilation (as with Euparia castanea also on S.invicta), or by plundering ant booty (!)

The next question would be akin to bats and moths- how do fire ants defend against this, has there been an evolution of back-and-forth defensive/offensive strategies, do they bother, or is there some sort of advantage to keeping them around?
